" 2. Microterys cincticornis Ashmead, new species. 



" This species probably represents a variety of the European M. 

 iesselatus Dalman. It agrees with it in stature and in wing markings, 

 except that the triangular white marginal spots are connected so as to form 

 an additional band, while the head and thorax at sides, too, are quite 

 differently coloured. The head, the pronotum, except above, the sides of 

 the thorax and the legs are brownish-yellow, while the mesonotum is 

 metallic-blue. 



" lype : Cat. No. 4769, U. S. N. M. (Ashmead collection). 



^^ Habitat : New Hampshire: Mount Washington. (Mrs. A. T. 

 Slosson)." 



George B. King, in 1899, recorded this parasite from K. piibesce7is in 

 Massachusetts. I have not met with it in Illinois. Through the kindness 

 of Mr. J. C. Crawford, Division of Insects, U. S, National Museum, 

 Washington, D. C, I am able to offer the following descriptive notes on 

 this species, taken from the type and in comparison with the two co-type 

 females of M. speciosissimiis, species nova, described just beyond : 

 " cincticornis has the upper part of the head more reddish, the middle 

 more yellowish ; this yellowish colour shows on the back of the head and 

 on the under parts of the insect ; the scape is light — only the anterior 

 margin is dark ; the scutellum is very metallic — as much so as the 

 mesonotum ; legs all light ; what I will call the middle band on the wing 

 is dark and the apical band distinct, making the apical part of the wing 

 darker than in your species ; in your species the middle band is a series 

 of dark spots, but in Ashmead's species these are so close together that 

 they are hardly distinct from one another, being a band instead." (J. C. 

 Crawford, In litt.. January 8, 1909.) 



In cincticornis there is no tuft of hairs on the scutellum. 



4. Microterys speciosissitfius, species nova. 



Normal position. 



Female. — Length, 1.33 mm. Normal in size and shape; funicle 

 annulate, scape greatly dilated, scutellum without a tuft of hairs at apex. 



General colour ochraceous, the mesoscutum metallic dark blue, the 

 axillie and scutellum duller than the mesoscutum, purplish, the dorsum of 

 the abdomen the same colour as the scutellum, with a little more blue, 

 the abdominal ventum concolorous with the dorsum of abdomen, the 

 cephalic and caudal margins of the pronotum nearly concolorous with the 

 mesoscutum, leaving a narrow transverse intermediate portion ochraceous,
